"Bioware co-founder Dr. Ray Muzyka said Wednesday that the Mass Effect 3 team is already "working hard" to address concerns that players have had with the game's ending.

The game's executive producer, Casey Hudson, and his team "are hard at work on a number of game content initiatives that will help answer the questions, providing more clarity for those seeking further closure to their journey," Muzyka said in a blog post.

He promised more details on those initiatives in April. At this point, "we're working hard to maintain the right balance between the artistic integrity of the original story while addressing the fan feedback we've received," Muzyka said.

Mass Effect 3 sold 890,000 copies in its first 24 hours on the market, but in the weeks since its release, a growing number of fans have expressed disappointment with the game's ending. One fan was reportedly so peeved that he filed a false advertising complaint with the Federal Trade Commission.

Muzyka said Hudson and his team have "been poring over everything they can find about reactions to the game – industry press, forums, Facebook, and Twitter, just to name a few." That research will be used to create the upcoming content, which will be in addition to existing plans for more new full games.

"I'm honored to work with them because they have the courage and strength to respond to constructive feedback," he wrote. "I personally believe Mass Effect 3 is the best work we've yet created. So, it's incredibly painful to receive feedback from our core fans that the game's endings were not up to their expectations."

He also warned users not to engage in personal attacks. "We listen and will respond to constructive criticism, but much as we will not tolerate individual attacks on our team members, we will not support or respond to destructive commentary," Muzyka wrote"
